Tomcat與GlassFish用法大致相同，只有jar包的儲存位置有差異，步驟如下
●下載JDBC Driver
去
Microsoft JDBC Driver 4.0 for SQL Server下載sqljdbc4.jar
●把JAR包放到lib資料夾
◎Tomcat
放至Tomcat Server安裝位置的
lib資料夾，如果Tomcat安裝在C:\Tomcat\，那就放到C:\Tomcat\
lib
◎GlassFish
放至GlassFish Server其domain下的
ext資料夾，如果GlassFish安裝在C:\glassfish3\，且domain名稱為domain1，那就放到C:\glassfish3\glassfish\domains\
domain1\lib\ext
●定義persistence.xml
< ?xml version="1.0" encoding="UTF-8" ?>
< persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0" xmlns="http://java.sun.com/xml/ns/persistence">
< persistence-unit name="
jpa unit name" transaction-type="RESOURCE_LOCAL">
< provider>org.eclipse.persistence.jpa.PersistenceProvider</ provider>
< exclude-unlisted-classes>false</ exclude-unlisted-classes>
< properties>
< property name="javax.persistence.jdbc.driver"
value="com.microsoft.sqlserver.jdbc.SQLServerDriver" / >
< property name="javax.persistence.jdbc.url"
value="jdbc:sqlserver://

< property name="javax.persistence.jdbc.user" value="

< property name="javax.persistence.jdbc.password" value="

</ properties>
</ persistence-unit>
</ persistence>
